A solenoid with ends marked A and B is suspended by a thread so that the core can rotate in the horizontal plane. A current is maintained in the coil so that the electrons move clockwise when viewed from end A toward end B. How will the coil align itself in Earth's magnetic field?

When the electrons move in a clockwise direction, the current is flowing in an anticlockwise direction. When you see so, it means that at this particular end, there is a North pole.
